Toolbox Talk: Grounding Equipment

Date: [DATE] Duration: [DURATION] minutes Presenter: [PRESENTER NAME] Location: [LOCATION]

Objective

The objective of this toolbox talk is to educate participants on the importance of proper grounding of electrical equipment to ensure safety and prevent electrical hazards. By the end of this session, participants should understand the procedures for grounding equipment and the potential risks associated with improper grounding.

Introduction

Grounding is a critical safety measure in electrical systems, providing a path for fault current to safely dissipate into the earth. Proper grounding helps prevent electrical shock, equipment damage, and fire hazards. Recent incidents have highlighted the dangers of inadequate grounding, emphasizing the need for strict adherence to grounding protocols.

Presenter Note: Engage the audience by asking if anyone has personal experience related to grounding issues.

Key Points

  • Importance of Grounding: Grounding provides a safe path for electricity to travel in the event of a fault, reducing the risk of electric shock and equipment damage.
  • Equipotential Zones: Establishing equipotential zones is crucial when working on deenergized circuits to prevent hazardous potential differences [1].
  • Testing for Voltage: Always test lines and equipment to verify the absence of voltage before installing grounds [1].
  • Proper Connection and Removal: Attach the ground-end connection first and use a live-line tool for connecting and removing grounds [1].
  • Maintenance of Grounding Equipment: Regular maintenance is essential to ensure low resistance and effective grounding [2].

Hazard Identification

Common hazards related to improper grounding include:

  • Electric Shock: Can occur if grounding is not properly established, leading to severe injury or death.
  • Equipment Damage: Fault currents can damage equipment if not properly grounded.
  • Fire Hazards: Poor grounding can lead to overheating and potential fires.

Presenter Note: Encourage participants to share any additional hazards they've encountered.

Control Measures

Discuss the hierarchy of controls:

  • Engineering Controls: Use of equipotential zones and conductive mats to minimize potential differences [2].
  • Administrative Controls: Implement procedures for testing and verifying deenergization before grounding [1].
  • Personal Protective Equipment (PPE): Use appropriate PPE when working with electrical systems.

Safe Work Procedures

  1. Verify deenergization of equipment.
  2. Test for absence of voltage.
  3. Establish an equipotential zone.

Division 2 AO 2-2017 Oregon Administrative Rules Oregon Occupational Safety and Health Division - (d) While working on circuits deenergized under clearance conditions with multiphase lines, shorts and grounds must be established at the lowest impedance available. Employees may perform work on one phase of a multi-phase line after establishing an equipotential zone that includes the phase being directly worked on. The phases outside the equipotential zone are to be treated as energized with minimum approach distance observed, unless they become part of the equipotential zone. Note to paragraph (4): American Society for Testing and Materials Standard Specifications for Temporary Protective Grounds to Be Used on De-Energized Electric Power Lines and Equipment, ASTM F855-09, contains guidelines for protective grounding equipment. The Institute of Electrical Engineers Guide for Protective Grounding of Power Lines, IEEE Std 1048-2003, contains guidelines for selecting and installing protective grounding equipment. - (5) Testing. The employer must ensure that, unless a previously installed ground is present, employees test lines and equipment and verify the absence of nominal voltage before employees install any ground on those lines or that equipment. - (6) Grounding must be verified if an employee requests it. - (7) Connecting and removing grounds. - (a) The employer must ensure that, when an employee attaches a ground to a line or to equipment, the employee attaches the ground-end connection first and then attaches the other end by means of a live-line tool. For lines or equipment operating at 600 volts or less, the employer may permit the employee to use insulating equipment other than a live-line tool if the employer ensures that the line or equipment is not energized at the time the ground is connected or if the employer can demonstrate that each employee is protected from hazards that may develop if the line or equipment is energized. - (b) The employer must e…

Source excerpt

Division 2 AO 2-2017 Oregon Administrative Rules Oregon Occupational Safety and Health Division For underground systems, employers commonly install grounds at the points of disconnection of the underground cables. These grounding points are typically remote from the manhole or underground vault where employees will be working on the cable. Workers in contact with a cable grounded at a remote location can experience hazardous potential differences if the cable becomes energized or if a fault occurs on a different, but nearby, energized cable. The fault current causes potential gradients in the earth, and a potential difference will exist between the earth where the worker is standing and the earth where the cable is grounded. Consequently, to create an equipotential zone for the worker, the employer must provide a means of connecting the deenergized cable to ground at the worksite by having the worker stand on a conductive mat bonded to the deenergized cable. If the cable is cut, the employer must install a bond across the opening in the cable or install one bond on each side of the opening to ensure that the separate cable ends are at the same potential. The employer must protect the worker from any hazardous differences in potential any time there is no bond between the mat and the cable (for example, before the worker installs the bonds). - 3. Other safety-related considerations. To ensure that the grounding system is safe and effective, the employer should also consider the following factors: 5 - i. Maintenance of grounding equipment. It is essential that the employer properly maintain grounding equipment. Corrosion in the connections between grounding cables and clamps and on the clamp surface can increase the resistance of the cable, thereby increasing potential differences. In addition, the surface to which a clamp attaches, such as a conductor or tower member, must be clean and free of corrosion and oxidation to ensure a low-resistance connection. Cables…
